Application tiled Kay 17, 1927. Serial No. 192,068.

This invention relates to heaters for hair waving outfits, and has foran object to provide an improved construction adapted to be used inconnection with my co-pending application for hair waving outfits.

Another object of the invention is to provide an improved heater forhair waving outfits, wherein the heater is formed so that it maybe'quickl applied or removed, and when applied, wi 1 almost surround thehair being treated.

A further object of the invention is to provide a simple heater for hairwaving outfits, wherein a partly tubularheating structure is formed,capable of fittingover coiled hair without any adjustment of the parts.

In the accompanying drawing Figure 1 is a perspective view of a heaterdisclosing an embodiment of the invention, a coil and certain otherparts being shown in dotted lines in connection therewith.

Figure 2 is a longitudinal vertical sec-- tional view through the heatershown in Fi re 1.

igure 3 is an end view of the heater shown in Figure 1.

Figure 4 is a sectional view through Figure 2, approximately. on line H.

Referring to the accompanying drawing by numerals, 1 indicatesthelead-in wires of the heater which are connected by screws 2 with theterminals 4 and 5 of the heating element 6. The heating element 6 issubstantially a half circle and is fitted into a casing 7 formedsubstantially as a half circle in cross section. The semi-tubularsection 7 may be manufactured in any deslred way, but is preferablyformed from a sectlon of tube bent so that part of the tube will formthe outer section 8 and part of the tube the inner section 9 with theconnectin edges 10 and 11 all of one piece. The end p ates 12 ,and 13may be spot welded in place, soldered or otherwise secured in place, soas to make a substantially water-tight and air-tight container for theheating element 6. The section 9 is a trifle over a half of a tube and,consequently, will readily fit over a shell 14. The shell 14 is mountedover the coiled hair to be treated and forms no part of the pres entinvention. The hair to be treated is wound on a tube or other support,covered with a moistened cloth having proper chemicals, and then theshell 14 placed 111 pos1- tion thereon. The heater embodying theinvention is then applied as shown in Figure 1, and the heat turned onand maintained on for the desired length of time. The heater may beplaced in position by a direct movement toward or from the shell 14.

Rigidly secured to the casing 7 is a metallic bracket or support 15which is spot welded or otherwise rigidly secured thereto at one end.This bracket is preferably provided with a threaded opening forreceiving the screw 3, which screw not only passes through this bracketbut through a supporting block 16, a clamping block 17 and a cord guideand guard 18. The guide and guard 18 is preferably of insulatingmaterial and is provided with an opening 19 through which the wires 1extend. This guide and guard may be secured to the bracket 15 in anysuitable manner, as for instance, by rivets 3'. The screw 3 acts toclamp the block 17 firmly against the ends of wires 1 so as to protectthese wires, as well as the terminals 4 and 5 and associated parts.Auxiliary screws 2 are used for mechanically and electrically connectingthe ends of wires 1 to the terminals 4 and 5, as shown in Figure 4. Thescrews 2 are threaded into the block 16.

In use, after the parts have been rgperly assembled as shown in Figure5: e device is ready for use and may be slipped over the shell 14 asdesired. In waving or curling hair, it is customary to wind the hair insmall bunches so that there will be usually twenty-five or more buncheson an ordinary size head. After the hair has been properly coiled andsupplied with the proper coverings, including the shell 14, a heater foreach coil is forced over the coil as shown in Figure 1. In other words,there are thirty coils for instance, there will be thirty heaters used,and it is customary to apply the heaters as the different coils havebeen finished, but the current is not turned on until all of the coilshave been properly formed and supplied with heaters. When this has beendone, the current is turned on to all of the heaters at one time. Afterthe current has been maintained on for the desired time, it is turnedoil and the heaters removed and used on the next customer if desired. Byproviding the casing 7 substantially water-tight, none of the moisturecan in any way affect the heating element 6, which may be of any desiredtype.

Also, there is no chance of an; injury being done to the heating elementor any of the.

other parts, as the casing 7 is made of metal and the blocks 16 and 17are of fiber or other suitable insulation.

What I claim is:

A heater for hair waving outfits, comprising a heating elementsubstantially arcshaped in cross sect-ion, a metallic casing coveringsaid heating element, abracket connecting with said casing adjacent oneend, a pair of insulating blocks associated with said bracket, saidheating element havin a pair of terminals extending between said blocks,a pair of lead-in wires extending between said blocks, means forconnecting the respective lead-in wires with said terminals, and meansfor clamping said blocks together and to said bracket for hoIding saidlead-in wires in proper position for protecting the respective partsadjacent the ends of the lead-in wires.
